The most recent US Department of Labor statistics indicate that nearly half of the number of mothers with infants under 1 year of age are working outside the home (The New York Times, March 16, 1986, p 25). This fraction is an increase over previous estimates, and there is reason to believe that this trend will continue. A variety of arrangements have been devised to care for these and older children, ranging from baby-sitting to more structured day-care centers. The objective of these arrangements is to allow parents to work. When children are ill, alternatives may be required. To address this need, day-care centers specifically designed to care for sick children are being established (Time, Feb 17, 1986, p 57). The exact number of well or sick children cared for in any of these arrangements is unknown. The proportion regulated and the degree of enforcement can only be surmised.
